For those that are disabled Veterans, Active Duty Military and Foster Families...you can camp for free at Oregon State Parks. All you have to do is submit the documents to the state parks and fill out the simple form. After verification they send you a Special Access Pass. That allows you to camp for free up to 10 days per 30 day period. If making on line reservations all you pay is the reservation fee and if you are taking an extra vehicle, you pay that fee.
It is simple and a great savings. I have saved hundreds of dollars. Thank you Oregon!
